Analysis and Control of Large-Shunt-Capacitor-Bank Switching Transients

Abstract

Large capacitor banks at medium-voltage levels are finding applications and greater acceptability in industrial distribution systems. However, these can give rise to current and voltage transients, stress the switching devices and insulation systems, and can be detrimental to the sensitive loads, i.e., drive systems. The paper discusses the methodology of the analysis and control of the switching transients. The results of the Electromagnetic Transients Program (EMTP) simulation are presented where applicable.
